Benefits of technology

"The patent text describes an articulable crankset for a convertible, pedal-powered vehicle that can be retracted to provide a more user-friendly experience when using the push-powered vehicle. The crankset has articulating arms that can move up to 180 degrees and is designed to be attached to a spindle and pedals on the vehicle. The crankset can be easily converted from a pedaling position to a retracted position to provide a more open space for the user's legs. The technical effect of this invention is to provide a more comfortable and efficient experience when using the push-powered vehicle."

Problems solved by technology

Training wheels have been used as the standard accessory for many years for teaching children how to ride a bicycle, and they continue to present problems that are all too familiar.
For example, training wheel modified bicycles wobble from side to side and make the child feel unstable; and, the child is often positioned so uncomfortably high in the air that the child has difficulty touching the ground.
Of course, one or a combination of these problems can create a situation that is quite terrifying to a child that is afraid to fall or that has fallen and doesn't want to get hurt again.
In addition, training wheel modified bicycles teach a child how to steer and pedal but, unfortunately, the child does not learn how to balance.
As such, the transition from a training wheel bicycle to a bicycle without training wheels can be daunting for anyone, since the sensation of balancing remains new and unfamiliar, and the fear of falling can be intense.
Although this may be somewhat inconvenient for younger, active parents, this can be quite troublesome and difficult for less active parents, older parents, and grandparents.
It may even be impossible.
Tricycles aren't a good answer to the problem, because tricycles are unstable and susceptible to tipping over due to the instability that is inherent to the three-wheel structure.
Also, tricycles aren't “a real bicycle” in the eyes of a child, and the child riding the tricycle does not learn the balancing that is required for the safe operation of a bicycle.
There are “push-bicycles” and “running bicycles” available on the market but these bicycles are either (i) not convertible from a pedal-powered bicycle to a push-bicycle, or (ii) do not leave the drive mechanism intact during the conversion, making the conversion inconvenient and difficult to perform, particularly when the user is in the process of using the bicycle.
Some of these bicycles are made almost entirely out of wood, such as the Skuut Balance Bicycle, and are not capable of conversion to a pedal-powered bicycle.
There is also the BMW Kids Bicycle, which is convertible into a push-bicycle, but the drive mechanism does not remain intact.
In addition, these bicycles can also have abrupt and discontinuous surfaces exposed to a child's legs, causing discomfort and possible injury to the child's legs, even after removal of the cranks or crankset.

Embodiment Construction

[0030]The teachings provided herein relate to an articulable crankset for converting a pedal-powered vehicle into a push-powered vehicle having the articulable crankset in a retracted position to provide at least less of an obstruction to a user's legs during use of the push-powered vehicle than a non-retractable crankset.

[0031]In some embodiments, the teachings are directed to an articulable crankset for a convertible, pedal-powered vehicle. FIGS. 1A and 1B illustrate an articulable crankset in a position for pedaling and in a retracted position, according to some embodiments. Since the crankset is articulable, the crankset can be releasably fixed in a variety of positions, where the choice of position is selected based on the user's preferred use of the vehicle. For example, the “position for pedaling” is a reversibly or releasably fixable position, such that the joints between the crankset components can be reversibly or releasably fixed in position using any method known in the ...

Abstract

The teachings provided herein relate to an articulable crankset for converting a pedal-powered vehicle into a push-powered vehicle having the articulable crankset in a retracted position to provide at least less of an obstruction to a user's legs during use of the push-powered vehicle than a non-retractable crankset. The vehicle can be a bicycle, and the articulable crankset can be a component of a production bicycle or a component of a conversion kit that will convert a bicycle from a pedal-powered bicycle to a convertible bicycle that can also function as a push-powered bicycle.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The teachings provided herein relate to an articulable crankset for converting a pedal-powered vehicle into a push-powered vehicle having the articulable crankset in a retracted position to provide at least less of an obstruction to a user's legs during use of the push-powered vehicle than a non-retractable crankset.[0003]2. Description of Related Art[0004]Most everyone has experienced learning how to ride a bicycle as well as witnessed watching, or even teaching, a child how to ride a bicycle. During the process of learning how to ride a bicycle, one of the goals is to reduce or eliminate fear, hesitancy, or rejection of biking. Training wheels have been used as the standard accessory for many years for teaching children how to ride a bicycle, and they continue to present problems that are all too familiar. For example, training wheel modified bicycles wobble from side to side and make the child feel unstable; and, the child is often p...
